I recently acquired an old Aspen hollowbody electric guitar. The neck pickup seems to play fine through my amp, but when I switch the selector to the middle position and the bridge position I loose signal. There are volume and tone controls for each of the pickups, which I have tried fiddling around with to no avail (they work for the neck pickup, have no affect on non-functional bridge pickup).

I have been playing guitar for a while, but have never switched out any electronics or done any sort of repair. I would love to learn how to repair this myself but have no idea where to start. Does anybody have any suggestions where to start / how to diagnose the problem / if this is even doable for a newbie?

Additional information
The pickups are humbuckers
I see no plate to gain access to the inside, I've heard this means I will need to go though the sound hole / input jack
I have a soldering gun but very little experience soldering
The guitar is pretty old, I'd say made in the late 80's

As a guitar tech, I can tell you that if you have open windings in a pickup you cannot easily rewind or find the break. If you've got a bad switch or disconnected wire, you can fix it. My advise is let a tech do it. Then again, you can shotgun the problem and just install new pickups wherever you find a dead one. Lindy Fralin who is the Wizard of pickup building can rewind bad pickups. I had an antique Lap Steel with a bad pickup and I didn't want to destroy the value so I got him to rewind it.

I would automatically check the selector switch first. It may have lost a tang or a wire has come unsoldered rendering the middle position silent, much cheaper than new pickups unless you need an excuse..;-)
